Effect of Ozone Therapy for the Treatment of Digital Ulcer in Patients With SSc

Functionality in patients with SSc? Systemic Sclerosis (SSc) is a chronic connective tissue disease characterized by microvascular involvement, immunological dysfunction, extracellular matrix deposition in the skin and internal organ involvement. Vascular disease has an important role in the pathogenesis of SSc. Especially as a result of involvement of micro-vessel and digital arteries, digital ulcer (DU) formation may be seen. DUs are responsible for pain, poor quality of life, impairment of life activities and morbidity in patients with SSc. , they are correlated to disease severity and outcome. Approximately half of SSc patients have DU during the course of the disease. Recurrent DU is observed in 10% of the patients. In 75% of these patients, DU occurs 5 years after diagnosis. Patients with anti-SCL 70+ develop DU 5 years earlier than those with anti-centromere positive. The development of DU may take a long time to heal if there is underlying calcinosis. In a study, it was seen that the recovery of DU was 93.6 days if there is underlying calcinosis, and 76.2 days if not. DUs can be infected and thus complicated by osteomyelitis. In a retrospective study, it was reported that 42% of infected DUs were associated with osteomyelitis. DU management is a great challenge for the clinician and requires a multidisciplinary approach. Ozone has a place in medical use since the 19th century, as it is an oxidant and disinfectant. In recent studies, it has been reported to be antiviral and bactericidal. Therefore, it has indications such as coronary artery disease, chronic hepatitis and chronic low back pain. It has also been shown to have a positive role in trophic ulcer, ischemic ulcer and diabetic ulcer healing. The mechanism by which ozone therapy provides wound healing is not fully understood. In addition, it improves microcirculation in the capillary vessels by improving flexibility and stability of the cell membrane and limiting the aggregation and adhesion of platele
